Abstract: The observer-based output regulation for the linear switched singular systems is studied in this paper, both the full-order and reduced-order observer approaches are considered. Firstly, by introducing the full-order extended state observer to estimate the states of system and the external reference signals simultaneously, under some standard assumptions, feasible criteria for switched singular systems to achieve the output regulation goals are developed and the observer design methods are presented. Furthermore, based on the restricted system equivalent (r.s.e) transformation, a reduced-order observer is employed, under average dwell time (ADT) switching, feasible criteria for the transformed systems to satisfy the output regulation aims are presented and the procedure for designing the reduced-order observer is given. At last, an illustrative example is proposed to confirm the effectiveness of the developed results.
